MATTRESS.

Application led November 20, 1922. Serial No. 602,200.

To all 'LU/wm t may concern,

Be it known that I, ERNEsT W. ALDRIDGE, a citizen of the United States,residing at Vinson, in the county of Harmon and State of Oklahoma. haveinvented new and useful Improvements in Mattresses, of which thefollowing is a specification.

rIhe object of this invention is to provide an air mattress comprisingtwo independent longitudinal sections, each having an air inletcontrolled by the valve, so that one or both sections may be inflated,according to the need of the user.

A further object is to provide a mattress comprising two longitudinalsections of sheet rubber, covered with cloth1 with transverse strips andfastening devices for connecting the sections in such manner that bothwill lie in the same parallel plane when inflated, the strips or strapsbeingdisconnected when one section only is used, in order that the oneused portion may be folded over the other, and allowed to remain idle.

1With the foregoing and other objects in view, the. invention consistsin the novel construction and arrangement of elements described,illustrated and claimed, it being understood that modifications may bemade within the scope of the claims without departing from the spirit ofthe invention.

In the accompanying drawings, Figure 1 is a top plan view ofthemattress; Figure 2 is a side or edge elevation, and Figure 3 is avertical transverse section, broken away.

The two longitudinal sections of the mattress are designated 10 and 12,and each comprises four sides and two end walls. One side, which will betermed the bottom, eX- tends the full width of the mattress, and infact, a single width of sheet rubber may include also the edge portions12', the tops 13 and 14 for the two sections, and the inner edge portion15. The edges of the sheet of rubber as distinguished from the edges ofthe mattress sections, are secured under a central longitudinal strip16, just above the bottom thickness.

Middle reinforcing strips are designated 16 and ext-end entirely aroundeach mattress section and binding strips 18 reinforce all of thecorners. The opposite end walls of the sections are shown at 19 and 20.The mattresg so formed of sheet rubber is covered by a thickness offabric 22, and short straps 23 are secured by fastening devices 241, sothat the two sections may be directly connected when both are to beused. If only one section is required, the straps are released and theidle section is folded over the other.

Air inlet connections are shown at 25 and 26, in the end portions of therespective sections, and valves 27 close the connection. When deflatedthe mattress may be folded into very small compass, and is speciallyadapted for the use of campers, being readily inflated by any air pump,such as a tire pump, and not being affected by moisture. rIhe mattresswill be maintained in a sanitary condition; and is also adapted for usein hotels and in sleeping cars.

IVhat I claim is 1. A mattress comprising itwo longitudinal sections,hingedly connected, valved air inlet connections for the respectivesections, and means for connecting the sections ad jacent toone surfaceof the mattress, said sections being otherwise independent permittingthe sections to be folded over one another when inflated and whendeflated.

2. A mattress comprising two longitudinal sections, hingedly connected,valved air inlet connections, for the respective sections, meansconnecting the sections along a central longitudinal line adjacent toone surface of the mattress, and detachable devices for connecting saidsections near the oppo site surface of said mattress.

3. A mattress formed of two longitudinal sections including a singlewidth of material extending across the bottom of the two sections,thence along the outer edge portions and across the top of saidsections, inwardly to the center, and thence along the inner edges ofthe separate sections, downwardly to the bottom thereof, and detachablemeans for connecting adjacent portions of said sections.

In testimony whereof I aiiiX my signature.

ERNEST W. ALDRIDGE.
